The anterior choroidal artery (A.ch.a.) was studied in 140 hemispheres of the human brain. In 50 specimens the artery was cannulated and perfused with acrylic resin, in 20 specimens the A.ch.a., was selectively cannulated and perfused with dye. The artery then was microsurgically dissected and photographically documented. The site of origin of the A.ch.a.,(More)
BACKGROUND In self-renewing, pluripotent cells, bivalent chromatin modification is thought to silence (H3K27me3) lineage control genes while 'poising' (H3K4me3) them for subsequent activation during differentiation, implying an important role for epigenetic modification in directing cell fate decisions. However, rather than representing an equivalently(More)
Neutrophil extracellular traps (NETs) contribute to innate immunity as well as numerous diseases processes such as deep vein thrombosis, myocardial ischemia, and autoimmune disease. To date, most knowledge on NETs formation has been gathered via the qualitative microscopic examination of individual neutrophils in vitro, or aggregate structures in vivo. Here(More)
During 18 sellar and perisellar operations the optic tract was monitored by visual evoked potentials (VEP). Deteriorations of the cortical responses were recorded in 73%. In this patients there was no close correlation between the intraoperative findings and the postoperative visual function. Only in those patients who showed no remarkable intraoperative(More)
The succinate dehydrogenase (SDH) complex exerts a fundamental role in mitochondrial cellular respiration and mutations in its encoding genes (SDHA, SDHB, SDHC, SDHD, collectively referred to as SDHx) lead to a number of inherited endocrine cancer predisposition syndromes, including familial paraganglioma/pheochromocytoma. Recent studies suggest a possible(More)
The present case describes a two-step endoscopic management of hydrocephalus and diagnosis of a single pineal region metastasis arising from a gastric adenocarcinoma. A 62-year-old man presenting with signs of subacute obstructive hydrocephalus from a pineal region mass had at first been treated with an endoscopic third ventriculostomy. As cerebrospinal(More)
The successful targeting of neuroblastoma (NB) by associating tumor-initiating cells (TICs) is a major challenge in the development of new therapeutic strategies. The subfamily of aldehyde dehydrogenases 1 (ALDH1) isoenzymes, which comprises ALDH1A1, ALDH1A2, and ALDH1A3, is involved in the synthesis of retinoic acid, and has been identified as functional(More)
